PM高速钢CPM-M4粉末高速钢 高碳\合金钢
High speed steel belongs to high carbon high alloy ledeburite steel, special steel is with special heat treatment in the powder metallurgy high speed steel can obtain high hardness (HRC63 ~ 70), and, and, in 550 ~ 600 ℃ can still maintain a high hardness (HRC 60 or above), and high wear resistance of heat-resistant wear-resistant steel class, its main use for the fabrication of various machine tool cutting tools, mold is partly used in high load, high temperature air bearings and special alloy wear parts, etc.
Metallurgical powder high speed steel, powder metallurgy high speed steel, for short or PM high speed steel. By powder metallurgy method (atomized powder under the hot isostatic pressing treatment) was dense steel billet, then through forging, rolling, etc. The thermal deformation of high speed steel profiles, hereinafter referred to as powder high speed steel. Uniform powder high speed steel group, tiny grain, eliminates the fused cast high speed steel is difficult to avoid segregation, so than fused cast high speed steel of the same component has higher toughness and abrasion resistance,
高速钢属于高碳高合金莱氏体钢，是特殊钢中通过特殊热处理 粉末冶金高速钢可以获得极高硬度(HRC63~70),，而且在550~600℃仍可保持高硬度(HRC 60以上)和高耐磨性的耐热耐磨钢类，其主要用途为制造各种机床的切削工具, 也部分用于高载荷模具
粉末冶金高速工具钢由于其制造工艺的独特性, 与铸锻高速钢比较, 具有一系列优异性能。
